Patent GB-267629-A (GB)
Abstract: 267,629. White, A. E., (Remington Arms Co., Inc.). Dec. 22, 1925. Cash registers; printing totals; operationcounters. - In a cash register provided with clerks' and proprietors' controls, clerks' keys locked against unauthorized use may be freed by the proprietor's control lever when this is placed in a position additional to those determining the condition of the machine such as " machine locked," " drawer open," and " drawer closed." interlocks are provided to ensure correct manipulation of the lever and of the lid affording access to the totalizers, both in relation to each other and to the operative condition of the machine. The machine to which the invention is applied is described in Specification 135,465, (as open to inspection under Sect. 91 of the Acts), and Specification 157,824 is also referred to. Clerks' keys, controlling. Two clerks' keys 40, one of which must be operated as a preliminary to the entering of an item in the machine, each carry a pin 491, Fig. 1, so that by means of a clerk's lock 44 a corresponding lever 45 may be rocked to obstruct the pin and so prevent operation of the key. To enable the proprietor to free any such locked key, a lever 51 is mounted loosely on a shaft 21 and has a pin 52 disposed behind the levers 45. When the proprietor's control lever 56, Fig. 4, is suitably positioned, a shaft 54 is rocked to cause a cam 55 to shift the lever 51 clockwise displacing the clerks' levers 45 to present a slot 49 to the pins 491 and thus enable any clerk's key to be depressed. Access to record-strip and totalizers, controlling. The record-strip is arranged below a lid 78 hinged at its rear edge and normally held down by latches 87 fixed to a shaft 85 supported in a lid 82 pivoted at its lower end and serving by means of a shield 83 to cover the clerks' totalizers A, B. The latches engage lugs 89 on the lid 78 and also lugs 91 on the machine framing and thus normally maintain both lids locked. To release the upper lid 78 for replenishment of the recordstrip, a key may be inserted in a lock 93 and turned to rock the shaft 85 sufficiently to free the latches from the lugs 89 but not enough to disengage them from the lugs 91. For effecting- the complete rooking of the shaft 85 the proprietor's control lever must be positioned to " reset " so as through a cam 97 to rock a lever 99' counterclockwise and by means of a pin 95, otherwise serving to obstruct and limit the movement of the latches, to rock the latter clockwise to the full extent to liberate the lower lid 82 as well as the upper lid. Operation counters. When the lower lid 82 is opened the lid 106 covering the item and operation counters is released and a counter for the number of openings of the lid 82 is operated. The lid 106 is latched down by a oatch 107, Fig. 4, a pin 109 on which is urged by a spring 108 against an arm 110 fixed to a transverse shaft 102. As the lid 82 is opened a stud carried thereby and engaging a slotted cam 105 causes the shaft 102 to rock and consequently to displace the catch and free the counter lid 106. A link 111 attached to the arm 110 simultaneously operates a counter 1110, Fig. 1. Printing totals. For this purpose the frame 701, Fig. 4, carrying the record-strip is rocked forward to take an imprint from one of the totalizers. Normally this movement is prevented by an obstructing arm 113 fast on a shaft 103 arranged in alignment with shaft 102. A spring 114 connecting an arm 115 on shaft 102 with arm 113 forms a yieldable connection between the two shafts to allow shaft 102 to rock even if shaft 103 is locked. When the lower lid 82 is opened and shaft 102 rocked, as explained in the preceding paragraph, the arm 113 is removed and the frame 701 may be operated. To lock the amount keys at this time an arm 117 secured to shaft 103 is arranged to enter the path of an arm 118 rigid with the coupler 22. It will be noted that if the coupler has been displaced the above-mentioned yieldable connection permits shaft 102 to rock independently of shaft 103 and therefore enables the lid 82 to be opened. Proprietor's control lever. This consists of a bell-crank lever 56, Fig. 4, loose on shaft 31 and carrying an arcuate plate 57 provided with a pointer 552 co-operating with an index plate 59, Fig. 5. A rotatable barrel lock 551 is mounted on the plate 57 and by means of a flange cooperates with a stationary notched plate so as to free the lever 56 and lock it in any of its positions of adjustment. The movements of the lever are conveyed to shaft 54 by the gearing shown in Fig. 4. To prevent displacement of the lever from " reset " while the lower lid 82 is open, the shield 83 carried by the lid is provided with a plate 122 adapted to obstruct the lever 99 and so prevent return of the control lever. While the lid is being closed the curved edge of plate 122 passes below the lug 123 on the lever 99 and maintains the obstruction until the lid is fully closed, whereupon the other end 121 of the plate comes below the lug and frees the lever 99 and at the same time serves to prevent raising of the lid 82 so long as the control lever is not at " reset."
